I’m not entirely sure, but I suspect you’re asking us to add the ability to apply volume and pitch adjustments to individual sound def entries in FMOD Designer. We will not be adding that feature. All pitch and volume adjustments made in Designer are applied in real time when your game is run, and so increase the amount of resources that your project uses; We therefore recommend that our users "bake in" any pitch or volume adjustments that their sound files need, and use Designer’s automation and randomization tools only to apply adjustments that reflect randomization or variable in-game states. (As you may have observed, FMOD Studio does give you the ability to adjust the pitch and volume of individual playlist entries, but we recommend that users only use these features where necessary to support their use of nested and referenced events, and other referenced sound modules.)

If you were asking something else, please excuse my misinterpretation of your words.
